DC handheld resistance tester
Model KM OHM 8502
Handheld DC resistance tester, also known as transformer DC resistance
tester, DC resistance fast tester, ground continuity tester, adopts
microprocessor technology, four-wire method for testing, safe, precise and
reliable. Mainly used to measure the resistance of transformer windings,
transformer winding resistance, grounding down conductor continuity test,
cable wire resistance, switches, connectors, contact resistance of relays,
coils, motors, and equipment casings, lightning protection belts, and ground
Connection resistance test between metal components of beams, structures,
cabinets, steel bars, water pipes, windows, guardrails, radiators, assembly
lines and other objects. It is widely used in telecommunications, electricity,
meteorology, computer rooms, oil fields, power distribution lines, tower
transmission lines, gas stations, factory grounding grids, lightning rods, etc.
Handheld DC resistance tester is composed of a host, monitoring software,
test lines, communication lines, etc. The handheld and portable design of
the host is convenient for on-site application, with charging function, no need
to find electricity on site, full-color large-screen LCD display, clear at a glance,
convenient and easy to use touch screen operation, and port overload
prevention function. Large-capacity storage of 500 sets of data, resistance
measurement range : 10.0mΩ-50.00KΩ, measurement accuracy : 0.2%. The
upper computer software has functions such as historical data reading,
consulting, saving, and reporting.
